If the area to be covered for TV telecast is doubles then height of transmitting antenna (TV tower) will have to be:

(A) : The area to be covered for T.V. telecast is doubled, then the height of trans - mitting antenna will have to be doubled (R) : For T.V. signal propulation covered is equal to product of population density abd area covered

(A) : Greater is the height of T.V. transmitting antenna, greater is its range. (R) : The range of T.V. transmitting antenna is proportional to square root of its height.

If height of transmitting tower increases by 21% then the area to be covered increases by
